ARGYLE | PINK DIAMONDS
Discover our carefully curated selection of rare pink diamonds from the Argyle mine. Each diamond is accompanied by certificates from both Argyle and GIA (Gemmological Institute of America).
MILLIONS OF CARATS. ONLY A FRACTION IN PINK.
Since 1985, the Argyle mine in Western Australia has been among the world’s most significant sources of diamonds. Each year, it yielded millions of carats of rough diamonds, quickly establishing itself as one of the largest mines globally. But what truly made Argyle legendary were the pink diamonds – a beauty unmatched by any other mine in the world.
For decades, Argyle accounted for 90% of the world’s total supply of pink diamonds. And yet, they remained extraordinarily rare. Out of the 8–13 million carats extracted annually, pinks made up only around 0.01% – equal to just 800–1,300 carats. An annual quantity of only 160–260 grams. So little, in fact, that the entire world’s production of Argyle pink diamonds for a whole year could fit discreetly inside a spectacle case. And only a small portion of these stones were of gem quality.
When the mine closed in 2020, the world lost its most consistent source of pink diamonds. Since then, demand has risen dramatically – especially among collectors, jewellery connoisseurs, and investors who have seen the value of these unique stones soar. Today, Argyle pink diamonds are regarded as one of the most coveted and exclusive investment assets in the global jewellery market – and their rarity means they often vanish from the market as soon as they appear.
SILENT LUXURY IN ITS PUREST FORM
Argyle pink diamonds represent not only rarity, but a redefinition of luxury itself. In a world where opulence is often measured in size, volume, and recognizable names, Argyle pinks stand apart: discreet, understated, and profoundly rare.
True luxury is never shouted – it is felt by those who understand. It is the privilege of wearing something that not everyone can identify, but that the discerning few value beyond measure. An Argyle pink diamond embodies precisely this: a hidden signature of exclusivity, where the truest privilege lies in knowing you own something the world can never recreate.
Since the closure of the Argyle mine, this expression of luxury has become even more coveted. For collectors and investors alike, an Argyle pink is more than an acquisition – it is an entry into a discreet global circle, where value is carried in silence, yet never overlooked.
TENDER COLLECTION | ARGYLE
The Argyle Tender was an annual and highly exclusive presentation of the finest and rarest diamonds unearthed from the Argyle mine each year. The first Tender took place in Antwerp in 1985 and featured just 33 diamonds. By the following year, Geneva was added as a viewing location, and as interest grew, cities such as New York, Hong Kong, London, Perth, and Tokyo became part of the international showcase.
From 1985 to 2021, between 50 and 70 of the most exceptional pink, red, blue, and violet diamonds mined annually at Argyle were offered for sale through this prestigious auction. Since 2008, the most remarkable stones in each Tender collection have been given names reflecting their historical significance.
This exclusivity underscores the extreme rarity of Argyle’s pink diamonds—mine data indicates that, on average, only one carat of Tender-quality diamond was discovered for every one million carats of rough diamonds extracted from the mine.

NATURE’S RARE TREASURES
Limited supply
Only a tiny fraction of all diamonds mined worldwide are naturally colored, with pink diamonds making up less than 0.01% of that number. A large share of the world’s pink diamonds have come from the Argyle mine in Australia, known for producing over 90% of all pink diamonds. This mine closed in 2020, further restricting supply and increasing their value. Certain stones have seen remarkable price increases – for example, the rare pink diamonds from the Argyle mine have risen by as much as 500% over the past 20 years.
Unique color formation
Until recently, the cause of the pink color in diamonds remained a scientific mystery. Unlike other colored diamonds – such as green, blue, or yellow – the pink hue is not caused by trace elements within the diamond’s structure. Instead, some scientists believe that an atomic distortion in the crystal lattice selectively absorbs light, creating the pink coloration. The precise cause, however, is still unknown.
Strong demand
As the supply of natural pink diamonds continues to diminish, demand is rising sharply. The closure of the iconic Argyle mine in Australia in 2020 – the world’s primary source of pink diamonds – has had a historic impact on the market. With only a fraction of the world’s diamonds naturally occurring in pink hues, these gems are becoming rarer with each passing day.
Collectors, investors, and connoisseurs across the globe seek pink diamonds for their color intensity, rarity, and proven ability to retain – and often increase – their value over time. Their appeal lies not only in their beauty but also in their status as an investment of the highest calibre.
KEY HIGHLIGHTS | WHAT YOU SHOULD KNOW
Rarity
The rarer a diamond, the more valuable it becomes – and the stronger its potential as an investment. In most cases, the focus should be on acquiring a single exceptional diamond rather than several smaller ones.
Certification
Always purchase with a GIA (Gemological Institute of America) certificate to ensure global marketability. If the diamond originates from the Argyle mine, an Argyle certificate should accompany it.
Financial advantages
For private buyers, any potential return is tax-free if the diamond is set in jewellery. When stored in a bonded vault outside the EU, the investment is exempt from VAT for private investors.
Time horizon
Investing in diamonds is a long-term strategy, typically requiring a time horizon of 4–8 years.
ARGYLE COLOUR SCALE
Pink diamonds are primarily graded by the intensity of their colour – unlike white diamonds, where clarity is the key factor. The deeper and more saturated the colour, the rarer and more valuable the diamond. Diamonds from the Argyle mine occur naturally in a wide range of shades – from delicate rose tones to vivid, intensely saturated pinks, as well as the rare hues of purplish red and red.
Purplish Pink (PP) – Pink with a purple overtone.
Scale: 9PP (light) → 1PP (intense).
Pink (P) – Pure pink colour.
Scale: 9P (light) → 1P (intense).
Pink Rosé (PR) – Pink with a soft rosé nuance.
Scale: 9PR (light) → 1PR (intense).
Red & Purplish Red – The rarest colours on the scale.
Pink Champagne (PC) – Pink with brown undertones.
Scale: PC1 (light) → PC3 (darker).
Blue Violet (BL) – Rare hue with a blue/purple tone.
Scale: BL1 (light) → BL3 (intense).

A GLIMPSE IN A TERMITE MOUND
Forty years ago, in the Kimberley region of Western Australia, two geologists, Frank Hughes and Warren Atkinson, made a remarkable discovery in a termite mound: a small diamond. What the termites had unearthed would turn out to be the beginning of one of the world’s richest diamond deposits. After ten years of intensive exploration – with samples collected from rivers and streams, and long stretches in remote and inaccessible terrain – they finally located the site where the Argyle mine would be established. A mine that would go on to produce some of the world’s most coveted pink diamonds.
